Since you need nano anyway (interfacing is very difficult otherwise),
you can of course map the structures, and create user-specific
translators, which communicate in common code (OpenGL for artificial
reality, so to speak).

Of course if you have nano you don't need such crude things, but in
theory it is a possibility.
